:Application filed September 30,1927. SerialNo. 223,107.

This invention relates to ,hook bars for footingmacl'lines, .andhas foran object to provide an improved construction wherein means are provided whichwill not tear or distort:tl1e knit portion of the stocking.

Another object of the invention is to provide a hook bar wherein clamping means are presented for clamping 0r grippingthe thin or sheerpa-rtpf the stocking so, as to maintain the same under tension without danger oftearingxor distortingany of the loops of the stocking.

A further object of the invention is to provideahook bar, .wherein the usual hooks are provided at the ends for engaging the heel section of the stocking, with special gripping meanscentrally for gripping the centerpart of the stocking by a clamping action.

Referring to the accompanying drawings by numerals, lindicates a footingmachine ofa well known make. This machine is pro vided with a rod-2 adapted to receive the drum 3 and guidingrod ll. Themac hine is also provided with the usual welt bar 5 and a sinker 5. All of theparts just described are old and well known, and therefore, form no part oftheinvention except in combination.

As indicated in Figure 1, the stocking body 6 overlies the drum 3, rod 1 and associated parts. The heel end of the stocking body 2 is arranged in the machine in the usual manner, whereby the foot may be knit in place as usual. Heretofore, hook bars were used for providing tension on the parts beneath the welt bar 5. In the bars heretofore used, sometimes three and sometimes four or more hooks were provided, arranged jaw or gripping member 22.

atspaced intervalsialong thebar and hooked into different parts of the stocking body 6. lnthe present invention, a hook bar 7 is provided, ,prei'erablyof the same length as the bars heretofore used. This hook bar is provided with hooks 8 and 9 similartorthe hooks heretofore used, said hooks 8 and 9 beinghookedinto or interlocked with the heel portions 10 and 11 of the stocking.

These heel portions are made of cotton or heavier :silk, while the main ,body of the st-ockingis of silk and sometimes thethrieads are very delicate where a sheer stocking is produced. :Heretofore, hooks similar to hooks v8,,anol 9 were hooked into or ,interlocked with the sheerpartof the stocking and, consequently, theloops wouldbe pulled out of place and sometimes -broken,.,so that the result would be afaulty stocking. took ings ofthis kind are soldas seconds and at, a much reduced price. In order toeliminate or reduce, the number of seconds, bar 7 in the present invention, is;providedionly with the end hooks. 8 and 9, andat-the center, with what may be .termed a gripping or clamping structure 12. This structulfifis shown more particularly in Figures 3 to 7 inclusive.

.The bar 7 is a flat pieceofimetal and the clamping-structure 12 is provided ,with a. web or plate 18 merging intoa tubular portionli cutaway at 15 for .providinga notch which extends almost through the tubular portion 14. Suitable screws ,16 secure the plate ,13tothe bar .1. The tubular portion ld'iis divided .into sections 17 and 18, sectionl'? havinga grippingmember 19 formed preferably of rubber and made preferably tubular. The gripping member or jaw 19 may be .held in place by friction, cement or otherwise. Prefer ably the section 1'? is open at the [end oppositenotch ,15, while, section 18 is closed at theend opposite notch 15, whereby the springQO may beinserted and caused ,toract on the follower 21 which carries a rubber This rubber jaw or gripping member is preferably provided with a rounded face 23, whereby part thereby grip in a better manner part of the stocking body 6 as illustrated in Figure 1. The jaws 19 and 22 are preferably of comparatively soft and yielding rubber so that they will yield and spread somewhat as they come to a gripping position, whereby fill thereof may project into the bore 2 1 and Lit:

none of the yarns and loops of the stocking body are injured or misplaced. The gripping action is produced by the spring 20, which is, of course, yielding, and which may be of any desired strength so as to produce any desired tension. The follower 21 is provided with a handle extending through a spiral-shaped slot 26 formed in section 18. This spiral arrangement of the slot is so that the workman may place his finger or thumb on the handle 25 and force the same downwardly. This will cause a movement of the follower 21 and jaw 22 against the action of spring and, consequently, away from jaw 19. A portion of the stocking body (3 is forced between the jaws and then handle 25 released. J aw 22, under the action of spring :20, will immediately move forward and grip the stocking. This movement is a partial rotary movement by reason of the slot 26 and handle It will thus be seen that the stocking is gripped or held by the two hooks 8 and 9 and by the grip or gripping structure 12. The body or plate 7' of bar 7, is provided with a slot 27 as usual, which accommodates the tape 98, said tape being secured to the section .29 of bar 1 by being wrapped around the section and stitched in place or otherwise secured as shown in Figure 2. The 0pposite or free end of the tape :28 is fitted at 30 in a suitable gripping structure in drum 3 so that as drum 3 rotates, tape 28 will be pulled. In this way there is a continuous tension on the hook bar 7, said tension, of course, being comparatively slight but suflicient for the purpose and also sufficient to feed the stocking as the knitting operation proceeds. In the drawing, a single gripping structure 12 has been illustrated and described, as ordinarily the hooks 25 and 9 and one centrally positioned gripping structure are sullicient to provide for the proper tension on the stocking. It will, however, be understood, that if desired, two or more gripping structures could be provided and distributed more or less evenly along the body 7.

What I claim is:

1. In a hook bar for footing machines, a body, a clamping structure connected to said body, said clamping structure including a yielding stationary jaw and a yielding movable jaw, manually actuated means for moving the movable jaw away from the stationary jaw, and automatically acting means for moving the movable jaw toward the stationary jaw.

2. In a hook bar for footing machines, a body and a clamping structure connected to said body, said elan'iping structure including a tubular member extending substantially, parallel with the body, said tubular member having a notch extending almost therethrough, a resilient jaw fitted into the tubular member and extending into said notch, a second jaw fitted into said tubular memher and normally extending into said notch, manually actuated means for moving said second jaw longitudinally of said tubular member away from said notch, and spring means for moving said movable jaw so as to clamp an article against said stationary aw.

3. In a hook bar for footing machines, a body, a tubular member mounted on said body having a notch extending almost through the tubular member at the center thereof whereby an opening is presented for receiving part of a stocking to be gripped, a rubber jaw mounted on one side of said opening and projecting into the opening, a rubber jaw mounted in said tubular member and projecting into the opening from the opposite side of the first mentioned jaw, a follower carrying said second mentioned jaw, a tubular member having a spiral slot, a handle extending through said slot for engaging said follower, and a spring positioned to urge said follower and the jaw carried thereby toward the opposite edge.

41. In a hook bar for footing machines, a body, a tubular member divided into two sections with a notch therehetween, a hollow rubber stationary jaw mounted in one section and extending into said notch, a rubber jaw arranged in the opposite section normally extending into said notch, a slot mounted in said second jaw an arm extend ing through said slot, a follower rigidly secured to said arm, said follower carrying said second jaw, and a spring arranged adjacent said follower for urging the follower toward the first mentioned jaw.
